Abstract
A fuel cell having a plurality of unit cells stacked in layers, each of the unit cells including an electrolyte and a pair of electrodes, each of the unit cells having a first primary surface and a second primary surface; a plurality of separator elements interposed between the adjacent unit cells, a fuel gas channel being formed on a side of the first primary surface of each of the unit cells and an oxidant gas channel being formed on a side of the second primary surface of each of the unit cells; and manifold portions each of which penetrates the separator elements in a thickness direction and gas-tightly communicates with each of the fuel gas channel and the oxidant gas channel through holes formed in the separator elements. Each of the manifold portions including a plurality of dielectric manifold ring, a plurality of spacer members arranged with the separator elements in a stacking direction and in contact with each other, and a manifold portion fastening mechanism for generating a fastening pressure for pressing the surfaces of the spacer members against surfaces of the associated separator elements. As a result, the surfaces of the spacer members and surfaces of the separator elements are held in mechanical contact with each other by the manifold portion fastening mechanism.
